BACKGROUND: Endometriosis (EMs) is a prevalent gynecologic disorder that often causes severe chronic pelvic pain and infertility. Although genome-wide association studies have identified common variants of EMs, the contribution of rare vari…
We aimed to examine abnormal oxidative lipid levels and their related mechanisms in EM-associated infertility. Through liquid chromatography tandem mass spectrometry analysis, decreased levels of epoxyeicosatrienoic acids (EETs), which have…
STUDY QUESTION: What molecular mechanisms underlie the decline in ovarian reserve as the number and quality of oocytes decrease in patients with ovarian endometriomas (OEM)? SUMMARY ANSWER: Elevated expression of the let-7 micro(mi)RNAs in…
Defective decidualization of endometrial stromal cells (ESCs) in endometriosis (EM) patients leads to inadequate endometrial receptivity and EM-associated infertility. Hypoxia is an inevitable pathological process of EM and participates in …
We aimed to determine the clinical outcome of double cleavage-stage embryo transfers in frozen-thawed embryo transfer cycles for older women.This study analyzed a total of 8189 cleavage-stage frozen-thawed embryo transfer cycles between Jan…
The mechanism by which endometriosis, a common gynecological disease characterized by chronic pelvic pain and infertility, causes infertility remains elusive. Luteinized unruptured follicle syndrome, the most common type of ovulatory dysfun…
BACKGROUND: Recurrent spontaneous abortion (RSA) is a common and complicated pregnancy-related disease that lacks a suitable biomarker to predict its recrudescence. METHODS: Tandem mass tag (TMT) analysis was conducted to obtain quantitati…
OBJECTIVES: The aim of this study was to investigate the impact of a history of recurrent ectopic pregnancy (EP) on pregnancy outcomes of subsequent in vitro fertilization (IVF) treatment. METHODS: A retrospective cohort study involving 45…
The implantation rate (IR) in assisted reproductive technologies such as in vitro fertilization (IVF) and intracytoplasmic sperm injection is affected by many different factors such as age, quality of embryo, and stage of embryo development…
Endometriosis an important cause of female infertility and seriously impact physical and psychological health of patients. Endometriosis is now considered to be a public health problem that deserves in-depth investigation, especially the et…
PURPOSE: The study was designed to evaluate whether cumulus cell removal 4 h post-insemination could influence fertilization and embryo quality. METHODS: The study included 61couples undergoing standard long down regulation protocol from J…
